First thing to know it is not 30" as advertised. It measures only 29.25" wide. I considered returning just on this fact but I didn't see that it was worth the trouble or inconvenience. The lights are pretty weak and not very useful in a moderately lit room. Another oddity is no matter what button I press on mine it starts on the highest fan speed. Choosing low speed turns on high speed. Choosing it again shuts it off. Can only get low speed by turning on high speed and then choosing low. For the price it does look nice enough and high speed fan, while just a little noisy, seems too powerful for the 6" ducting.
